To all whom it may concern:

Be it known that I, NELSON S. HoPK1Ns,'a citizen of the United States, residing at Fort Wayne, county of Allen, State of Indiana,

lowing is a specification.

It has been found in the manufacture and operation of condensers that the greatest stress tending to break down a condenser is at the edges or corners of the sheets or strips forming the conducting portion of the condenser. i

The object of my invention is' the conis reduced to aminimum. I have accomplished this by so arranging the conducting of adj acent strips or sheets of conducting material are parated by a distance which is appreciably greater than the thickness of the sheets.

i For a better understanding of my inven tion, reference may be had to the accompanying drawing in which Figure 1 is a perspective View showing the bodying my invention; Fig. 2 is a plan-view showing the same form; and Fig. 3 shows another form of condenser embodying my iiiventiorn, 1

Referring to the construction shown in Fig. 1 the sheets a there shown are made of some conducting material such as tin foil and are oined together in any suitable manner to form one of the conducting members of the condenser; The sheets a may be each provided with integral extensions-if at one corner which form the terminals of the respective sheets. The other conducting memsheets b which aresimilar to the sheets a, and are provided with extensions 16 similar The sheets 6 are turned however so that the extensions t. are diagonally opposed to the extensions t of the plates a. Sheets 0 formed of any suit. able dielectricmaterial separate the conducting sheets a and b. I

As is clearly shown in the drawing, sheets a and b are iaterally displaced with respect to one another so that while the similar edges are parallel, the terminal corners of adjacent sheets are separated by a distance greater" than the length of the diagonal of one of the sheets. As a result of this construction parallel edges of adjacent sheets are separated by a considerable lateral distance, and the liability of the condenser to break down .between these edges is accordingly decreased.

The sheets of the dielectric 0 may be somewhat larger than the sheets (29 and b, if desired. For instance they may be made of a shape similar to that of the sheets a and b but of such size that a diagonal is equal to or greater than the distance between thev ter- ,provided with terminal extensions t t.

The stri )S a and b are se arated from each l i other by layers or sheets of dielectric c.

The sheets a, b and c. are rolled together.

to form a roll condenser. The strips c and b are displaced laterally however so'that the parallel edges of ad acent strips are separated by a distance considerably greater than the thickness of thedielectric strips 0 as is clearly shown in the drawing. With this construction if the ends of the conducting strips 0/ and l) .are separated somewhat more than the thickness of the dielectric strips 0, the edges of the conducting strips will be separated in all places by a distance greater than the thickness of the dielectric separating the I body of the strips.

What claim as new, and desire tosecure' by Letters Patent of the United States, is,

1. A condenser composed of sheets or strips of some conducting material arranged with edges parallel and separated by interposed strips of dielectric, the adjacent sheets or strips of conducting material being'so placed that the distance between similar edges is greater than the distance between the bodies of said sheets orstrips.

ZFA condenser composed of sheets or strips of some conducting material arranged with edges parallel and separated by interposed strips of r'iieiectric, ent sheets or strips of conducting material being so piaced that the distance between parallel edges is greater than the distance between the bodies of said sheets or strips.

3. A condenser composed of sheets or strips of some conducting material separated by interposed sheets or strips of dielectric, the sheets or strips of conducting material being so placed that similar edges are a uniform distance apart and so that no considcrable extent of the edges of adjacent strips are asclose together as the distance between the bodies of said sheets or strips.

4. A condenser composed of two or more sheets or strips of good conducting material arranged vwith edges substantially parallel and separated by strips of dielectric, adjacent sheets or strips of conducting material being bodily displaced laterally with respect to each other.

5. A condenser comprising active strips or sheets of conductive material arranged with edges parallel, interposed dielectric material, adjacent strips or sheets of diiler- 'ent polarities being displaced laterally with respect to each other so that no considerable extent of the edges of adjacent strips are as close together as are the bodies of said strips.

6. A condenser comprising substantially rectangular active conductive plates of opposite polarities and interposed dielectric material, said plates being diagonally displaced with reference to each other.

In witness whereof I have hereunto set my hand this fifth day of November, 1902.
